Abstract
In this paper, gold–platinum (Au–Pt) bimetallic nanotubes with different Au/Pt ratio are successfully synthesized through a simple wet-chemical reduction route in which tellurium (Te) nanowires serve as both sacrificial template and reducing agent. The hollow nanostructure of Au–Pt nanotubes is formed due to Kirkendall effect. The as-prepared Au–Pt nanotubes can be applied as catalyst for methanol oxidation reaction, and the results indicate that the Au–Pt nanotubes with an Au/Pt ratio of 1:1 show the best electrochemical catalytic performances. Furthermore, the catalytic activity of the Au–Pt nanotubes is also better than Pt nanotubes and commercial Pt/C catalyst.
